河床运动 meaning in English

bed movement

The improved scheme can ensure the south branch to be open to navigation and the flow here not to be broken in low water seasons , and it will have active effect on protecting the south branch and fuyuan town . this study is an attempt of applying three - dimensional mathematical model in analogue calculation and analysis of flow , sediment and riverbed movements in a long river reach . it is very important for the future thorough research , and has great significance for promoting the application of the three - dimensional model to resolve
本研究是三维数学模型对较长河段水流、泥沙、河床运动模拟计算分析的一次尝试，其对今后进一步深入研究和应用三维模型解决工程实际问题，完善模拟方法、提高模拟水平，真正发挥数学模型其省时、省力、灵活方便和模拟细腻等在研究水沙运动规律和河床变形等方面研究中优势具有重要的意义。
